Decentralized Power Control for Over-the-Air Computation with Phase Noise
Martin Dahl, Erik G. Larsson
Estimation of uplink channels is required for coherent over-the-air computation (OAC). When channel estimation is done using calibrated reciprocity, the estimates are only availabl…

A Unified Framework for Unbiased Non-Coherent Over-the-Air Computation
Martin Dahl, Zheng Chen, Erik G. Larsson
Over-the-Air Computation (OAC) enables efficient data aggregation in large-scale distributed systems by exploiting the superposition property of wireless multiple-access channels.…

Hybrid Channel Estimation with Quantized Phase Feedback for Over-the-Air Computation
Martin Dahl, Erik G. Larsson
To reduce the signaling overhead of over-the-air computation, a hybrid channel estimation scheme is proposed, where reciprocity-based and feedback-based channel estimation are comb…
